1. Merton Miller's work on capital structure theory challenged the traditional view that a firm's value is affected by its debt-equity ratio.
2. The Modigliani-Miller theorem, developed by Miller and Franco Modigliani, states that a firm's value is independent of its capital structure under certain assumptions, such as perfect capital markets and no taxes.
3. Miller's research demonstrated that in a perfect capital market, the cost of capital for a firm is unaffected by its financing decisions, as investors can replicate the firm's capital structure through their own personal borrowing and lending.
4. Miller's work highlighted the importance of considering the tax benefits of debt financing, as well as the potential costs of financial distress, in determining a firm's optimal capital structure.
5. Merton Miller's contributions to the field of finance have had a lasting impact on the way scholars and practitioners think about capital structure and the factors that influence a firm's value.

Review Questions

• Explain Merton Miller's key contribution to the concept of capital structure.
  • Merton Miller's key contribution to the concept of capital structure was the development of the Modigliani-Miller theorem, which challenged the traditional view that a firm's value is affected by its debt-equity ratio. Miller and his co-author, Franco Modigliani, demonstrated that in a perfect capital market with no taxes and no financial distress costs, a firm's value is independent of its capital structure. This was a significant departure from the prevailing theories at the time, which suggested that firms could increase their value by adjusting their debt-equity ratio.
• Describe the assumptions underlying the Modigliani-Miller theorem and explain how they relate to Merton Miller's views on capital structure.
  • The Modigliani-Miller theorem is based on several key assumptions, including perfect capital markets, no taxes, and no financial distress costs. These assumptions are central to Merton Miller's views on capital structure, as he believed that in such an ideal environment, a firm's financing decisions would not affect its value. Miller argued that investors could replicate a firm's capital structure through their own personal borrowing and lending, rendering the firm's financing decisions irrelevant. By relaxing these assumptions, however, Miller acknowledged that factors such as tax benefits of debt and the costs of financial distress could play a role in determining a firm's optimal capital structure.
• Evaluate the significance of Merton Miller's contributions to the understanding of capital structure and its impact on modern finance theory.
  • Merton Miller's contributions to the understanding of capital structure have had a profound and lasting impact on modern finance theory. His work, particularly the Modigliani-Miller theorem, challenged the prevailing views of the time and forced scholars and practitioners to rethink the factors that influence a firm's value. By demonstrating that a firm's capital structure is irrelevant in a perfect capital market, Miller's research highlighted the importance of considering real-world factors, such as taxes and financial distress costs, in determining a firm's optimal capital structure. This shift in perspective has been instrumental in the development of more sophisticated capital structure theories and has influenced the way finance professionals approach decisions related to a firm's financing mix. Miller's contributions have been widely recognized and continue to be a cornerstone of modern finance education and practice.
